Tools to check on traffic

I'm looking for some other (reliable) tools to monitor Internet traffic (inbound and outbound). Just to have knowledge of what other alternatives are out there.

I currently make use of TCPView, by Sysinternals.

Do you make use of any different tool, or do you stick with TCPView?


Thanks


Edit: I also forgot to ask if it would be possible, and how, to create a "simple" Windows Powershell script, that could detect applications wanting to communicate with the outside?
It may sound a silly thought of mine, though.

 

I use Microsoft's Network Monitor. Its output, like TCPView, is process-based and, like TCPView, it's also free. You can get it here: Network Monitor 3.3 is now available.

 

I'll take a look. But, for what I'm reading over the product page, seems quite interesting.


Thank you

 

could also look at wireshark.

 

Here are some Payware's (I have no experience with any of them.):

Here are some Freeware's (I have no experience with any of them.):

I only have experience (very Limited) with TCPView.

 

If you save the cap to a file, you can also use other forensic-like tools to analyze the traffic and extrapolate interesting details. For example, networkminer is pretty cool and free. There are many others, but each one seems to have its strengths.

 

Excellent tool thanks, just installed and it's quite good.

I'm slightly confused at all the connections to updates.agnitum.com though, in 5 minutes there's been 100's.
